Volvo S80 Oxygen Sensor Heater Issue

I have a S80 and had a similar problem with the check engine light and increased fuel consumption. I would check the oxygen sensors. Is the error message indicating a specific sensor?

The error message refers to the oxygen sensor heater. Is that the same issue you had? I'm just trying to narrow down the possibilities before taking it in.

Yes, the error was also related to the oxygen sensor heater element. Unfortunately, I was not able to fix it myself and ended up going to the workshop. They replaced the sensor and the problem was solved.

Thank you for the information. It seems a visit to the workshop is inevitable. I had to pay 95€ for repair. Good to know what to expect.
